[0002] During engine operation, in order to improve combustion and emissions, some gases inside the engine enter the cylinders from the intake manifold to participate in combustion. Many of these gases contain oil vapors, such as the exhaust gas from the crankcase and the exhaust gas participating in the EGR cycle. When these exhaust gases move to a lower temperature position in the intake passage, the oil vapors in the exhaust gases will liquefy and drip into the intake passage. Partially liquefied oil will accumulate in the intake passage, thus affecting the normal operation of the engine. Summary of the Invention

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following is for reference. Figures 1-4 An oil collection device 100 according to an embodiment of the first aspect of the present invention is described.

[0033] like Figure 1 and Figure 2 As shown, an oil collection device 100 according to a first aspect embodiment of the present invention includes: a container 10 and an oil pipe 20.

[0034] The container 10 has an oil inlet 11 and an oil outlet 12. The oil inlet 11 of the container 10 is configured to communicate with the intake passage 400 of the engine to collect the oil condensed in the intake passage 400. One end of the oil pipe 20 is connected to the oil outlet 12, and the other end of the oil pipe 20 is connected to the engine bottom case 300.

[0035] External air enters the engine cylinder through the intake passage 400, and the engine bottom case 300 is located at the bottom of the crankcase to seal the crankcase.

[0036] During engine operation, in order to improve engine combustion, increase fuel efficiency, and reduce harmful emissions, some exhaust gas will enter the cylinder from the intake passage 400 to re-participate in combustion.

[0037] For example, crankcase exhaust contains fuel vapor and engine oil vapor. To prevent crankcase exhaust from being directly emitted into the air and causing air pollution, and to improve fuel efficiency, crankcase exhaust will enter the cylinder through intake passage 400 to participate in combustion. In order to improve the engine combustion process and reduce engine harmful emissions, some of the engine combustion exhaust will enter the cylinder through intake passage 400 to participate in the cycle again.

[0038] During the process of exhaust gas passing through the intake passage 400 and entering the cylinder, when the exhaust gas flows to a cooler area, some of the fuel, engine oil, and combustion products in the exhaust gas will liquefy and drip into the intake passage 400, forming a layer of gel-like substance. As the vehicle 1000 is used for a longer period of time, impurities in the air and liquefied oil stick to the gel-like substance and continue to accumulate. The accumulated oil will obstruct the gas flow in the intake passage 400, and some oil will fall off and move with the airflow in the intake passage 400. When passing through the throttle valve, the oil will stick to the throttle valve, thus affecting the normal operation of the engine.

[0039] In this embodiment, by providing a container 10 connected to the intake passage 400, the liquefied oil in the intake passage 400 can be discharged into the container 10, and the oil can be stored in the container 10. This reduces the probability of oil accumulating in the intake passage 400, thereby improving the reliability of the engine during operation. By providing an oil pipe 20, the oil in the container 10 can flow into the engine bottom case 300 through the oil pipe 20. Thus, the oil will not accumulate in the container 10, thereby reducing the frequency of cleaning the oil collection device 100 by the user in daily use.

[0040] According to the first aspect of the present invention, the oil collection device 100 can collect liquefied oil in the intake passage 400 and guide the oil to the engine bottom case 300, thereby improving the reliability of the engine during operation and reducing the frequency of cleaning the oil collection device 100 by the user in daily use.

[0041] In some embodiments of the present invention, such as Figure 1 As shown, container 10 is located below intake passage 400 and connected to intake passage 400. Thus, under the action of gravity, oil in intake passage 400 can enter container 10, thereby further reducing the probability of oil accumulating in intake passage 400 and improving the reliability of engine operation.

[0042] In some embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the container 10 is provided with a tube 13, which is a tube-shaped structure surrounding the oil inlet 11. The cross-sectional size of the tube 13 decreases in the direction from the oil inlet 11 toward the inside of the container 10. Thus, the tube 13 can partially block the oil inlet 11. When the negative pressure at the oil inlet 11 is too great and the oil in the container 10 moves toward the oil inlet 11, the tube 13 can block the oil. At the same time, as the oil enters the tube 13, the cross-sectional size of the tube 13 gradually increases as it approaches the oil inlet 11. Therefore, more oil is needed to completely block the tube 13. When the oil cannot completely block the tube 13, the negative pressure will be transmitted to the side of the oil closer to the container 10, thereby reducing the negative pressure difference between the two sides of the oil. Under the action of gravity, the oil will pass through the tube 13 and fall back into the container 10. This reduces the probability of the oil in the container 10 being drawn back into the air intake channel 400.

[0043] In some embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the pipe section 13 includes a tapered section 131. One end of the tapered section 131 is connected to the periphery of the oil inlet 11, and the other end extends toward the inside of the container 10. The cross-sectional area of ​​the tapered section 131 gradually decreases in the direction from the oil inlet 11 toward the inside of the container 10. Therefore, the cross-sectional size of the pipe section 13 can be reduced in the direction from the oil inlet 11 toward the inside of the container 10, and the dimensional parameters of the tapered section 131 can be changed during product design to meet product design requirements.

[0044] In some embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the pipe section 13 also includes a constant diameter section 132, which is connected to the other end of the tapered section 131. The cross-sectional area of ​​the constant diameter section 132 remains unchanged in the direction from the tapered section 131 to the constant diameter section 132. By setting the constant diameter section 132, during the process of oil flowing into the container 10, the constant diameter section 132 can guide the oil to drip onto the oil outlet 12, reducing the probability of oil dripping onto the side of the container 10 and sticking to the side of the container 10. This reduces the difficulty for users to clean the oil collection device 100 and improves the user experience. In addition, the constant diameter section 132 can improve the structural strength at the connection between the constant diameter section 132 and the tapered section 131, thereby improving the reliability of the oil collection device 100 during use.

[0045] In some embodiments of the present invention, such as Figure 2As shown, the oil collecting device 100 also includes a filter element 121, which is disposed inside the oil drain port 12 and detachably connected to the container 10. By providing the filter element 121, the filter element 121 can filter the oil flowing out of the container 10, thereby reducing the probability of impurities entering the engine casing 300 and further improving the reliability of the engine during operation.

[0046] The filter element 121 is detachably connected to the container 10. When there are too many impurities on the filter element 121, the filter element 121 can be removed for cleaning or replacement to ensure that the oil collection device 100 can work normally.

[0047] In some embodiments of the present invention, the oil pipe 20 is threaded or snap-fitted to the container 10. This allows for a detachable connection between the oil pipe 20 and the container 10, and simplifies the assembly and disassembly of the oil pipe 20 and the container 10. Consequently, it facilitates cleaning of the oil pipe 20 and the container 10 during daily use, and improves production efficiency during production.

[0048] In some embodiments of the present invention, the oil pipe 20 and the container 10 are connected by clamps. The clamp connection is simple to operate and the clamp cost is low. By connecting the oil pipe 20 and the container 10 by clamps, production efficiency can be improved and production costs can be reduced.

[0049] In some embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the container 10 includes a main body 14, an inlet section 15, and an outlet section 16. The inlet section 15 is connected to one end of the main body 14, and the outlet section 16 is connected to the other end of the main body 14. The cross-sectional dimensions of both the inlet section 15 and the outlet section 16 are smaller than the cross-sectional dimensions of the main body 14. The oil inlet 11 is formed at the end of the inlet section 15 away from the main body 14, and the oil outlet 12 is formed at the end of the outlet section 16 away from the main body 14.

[0050] By making the cross-sectional dimensions of the main body 14 larger than those of the inlet section 15 and the outlet section 16, the storage volume of the container 10 can be increased. When the oil discharge efficiency of the drain port 12 is low, the probability of the container 10 becoming full of oil and flowing back into the intake passage 400 can be reduced. When some oil in the engine casing 300 is drawn back into the container 10, the oil will only flow back into the intake passage 400 when the container 10 is full, thus reducing the probability of oil in the engine casing 300 flowing back into the intake passage 400. This further improves the reliability of the engine during operation. In addition, the dimensions of the main body 14, inlet section 15, and outlet section 16 can be changed during the design process to meet product design requirements.

[0051] In some embodiments of the present invention, such as Figure 2and Figure 4 As shown, pipe section 13 is located within inlet section 15. This increases the distance between pipe section 13 and the oil surface in container 10, thereby reducing the probability of pipe section 13 contacting the oil surface in container 10, and further reducing the probability of oil in container 10 being drawn back into intake channel 400.

[0052] In some embodiments of the present invention, the oil inlet 11 is formed at the top of the container 10, and the oil outlet 12 is formed at the bottom of the container 10. In this way, the oil storage space between the oil inlet 11 and the oil outlet 12 is larger, thereby further reducing the probability that the liquid surface of the oil in the container 10 comes into contact with the pipe 13, and further reducing the probability that the oil in the container 10 is drawn back into the air intake channel 400.

[0053] In some embodiments of the present invention, such as Figure 3 As shown, the oil collecting device 100 also includes a drain bolt 30 and a drain gasket 31. The inner wall of the outlet section 16 is threaded, and the drain bolt 30 is threadedly connected to the outlet section 16. The drain gasket 31 seals against the drain bolt 30 and the periphery of the outlet section 16. This achieves a seal on the outlet section 16 of the container 10, allowing the oil discharged from the intake passage 400 to be stored in the container 10. During use, if there is too much oil in the container 10, the user can simply unscrew the drain bolt 30 to drain the oil. Thus, the oil collecting device 100 has a simple structure and eliminates the need for an oil pipe 20 and a connecting hole for the oil pipe 20 on the engine casing 300, thereby reducing production difficulty and costs.

[0054] The vehicle 1000 according to a second aspect of the present invention includes the oil collection device 100 described above according to a first aspect of the present invention.

[0055] According to a second aspect embodiment of the present invention, by providing the oil collection device 1000 described above according to a first aspect embodiment of the present invention, the reliability of the vehicle 1000 during operation can be improved.

[0056] In some embodiments of the present invention, such as Figure 1 As shown, the vehicle 1000 includes: an intercooler 200, the intercooler 200 having a heat exchange passage 210 and an outlet 220 communicating with the heat exchange passage 210, a container 10 being located at one end of the intercooler 200 where the outlet 220 is located and at the bottom of the intercooler 200, and an oil inlet 11 communicating with the heat exchange passage 210, wherein the intercooler 200 is connected in series with the engine intake passage 400.

[0057] During engine operation, excessively high temperatures within the intake manifold 400 can lead to poor combustion in the cylinders, thereby reducing engine performance. For example, the temperature of the gas entering the intake manifold 400 after turbocharging will be higher, and the temperature of the exhaust gas entering the intake manifold 400 after EGR (Exhaust Gas Recirculation) will also be excessively high.

[0058] In this embodiment, by setting up an intercooler 200, the intercooler 200 can absorb the heat of the airflow flowing through the heat exchange channel 210, thereby reducing the airflow temperature in the intake channel 400. As a result, the temperature of the gas entering the cylinder through the intake channel 400 can meet the combustion requirements of the cylinder. During the product design process, the cooling effect of the intercooler 200 on the airflow can be adjusted according to the different combustion requirements of the engine, thereby meeting more product design requirements.

[0059] When exhaust gas containing fuel vapor, engine oil vapor, or water vapor passes through the heat exchange channel 210, due to the temperature drop, liquefied oil will drip into the heat exchange channel 210. Under the blowing of the airflow in the heat exchange channel 210, the oil in the heat exchange channel 210 will flow towards the outlet 220. In this embodiment, by connecting the oil inlet 11 of the container 10 to the bottom of one end of the outlet 220 of the intercooler 200, the oil in the heat exchange channel 210 can be discharged into the container 10 under the action of gravity, thereby reducing the probability of oil accumulating in the heat exchange channel 210.

[0060] In some embodiments of the present invention, the container 10 is threadedly connected to the intercooler 200. The threaded connection is detachable, secure, and easy to operate, thereby facilitating the user to disassemble the container 10 for cleaning during use and ensuring the reliability of the connection between the container 10 and the intercooler 200.

[0061] In some embodiments of the present invention, the vehicle 1000 further includes a turbocharger (not shown in the figures) and a breather (not shown in the figures), both of which are connected in series on the engine intake passage 400. A container 10 is disposed between the turbocharger and the breather, and an oil inlet 11 is connected to the intake passage 400. The breather is connected upstream of the turbocharger in the direction of airflow on the intake passage 400.

[0062] A turbocharger pressurizes the airflow within the intake manifold 400, thus improving the mixing of the airflow with fuel upon entering the cylinder, thereby improving combustion and enhancing engine performance. A breather vents gases from the crankcase, stabilizing the crankcase pressure and allowing the engine to operate normally.

[0063] During engine operation, under the action of the breather, the exhaust gas in the crankcase enters the intake passage 400. After being pressurized by the turbocharger, it enters the cylinder along with the gas in the intake passage 400. This improves the mixing degree between the exhaust gas in the crankcase and the gas in the intake passage 400, thereby improving the mixing degree of the air-fuel mixture in the cylinder and improving combustion in the cylinder. Furthermore, the pressurized airflow will not impact the breather, thus improving the reliability of the breather during operation.

[0064] When the external ambient temperature is low, fuel vapor, oil vapor, or water vapor in the crankcase exhaust gas in the intake passage 400 will liquefy, resulting in oil dripping into the intake passage 400. In this embodiment, by placing the container 10 on the intake passage 400 between the turbocharger and the breather, the oil in the intake passage 400 can be discharged into the container 10 through the oil inlet 11, thereby reducing the probability of oil accumulating in the intake passage 400 and improving the reliability of the engine during operation.
